Paper Abstract

The dynamic analysis using computational models is an important tool to simulate the dynamic of structures that have specific uncertain behavior like the cable stayed bridges which nowadays is an alternative to solve long span bridges with a slim structure. In this work we developed a 3D non linear model of a cable in order to evaluate the wind effect on the Papaloapan cable stayed bridge located on Veracruz Mexico, under different scenarios. The health of the structure is an important factor to analyze and there are many different fail causes, one of them is the fatigue fall that is relevant in the anchorage elements of the cable stayed bridges. It is possible to modify the behavior of the structure using dampers to minimize that effect. The geometry and all the forces and stress on the structures are a challenge also for the specialists of the structures, in this work the developed methodology resulted very successful to analyze the behavior of a cable on a cable stayed bridge using damping.
